Trying to use FindControl

Guest

I am trying to get the text of an item in a GridView, but am doing something
wrong. Can someone help me with the correct C# statement I need? Below is my
GridView and my attempt to get the control. Thank you.

string option =
((TextBox)dgDropDownMenus.Items[e.Item.ItemIndex].FindControl("txtName")).Text;

Hi,
It should be:
DataGrid dgDropDownMenus= (DataGrid)sender;
if(e.Item.ItemType.ToString() != "Header" && e.Item.ItemType.ToString() !=
"Footer")
{
string option = ((TextBox )e.Item.FindControl("txtName")).Text;
}

Although i have written this code for Datagrid, you can use same for
gridview with little or no modification.

I had to change your code where you had the "as TextBox" because it caused an
error to the following:

this.dgDropDownMenus.EditItemIndex = e.Item.ItemIndex;
TextBox option =
(TextBox)dgDropDownMenus.Items[this.dgDropDownMenus.EditItemIndex].FindControl("txtName");

Then I got the following error: error: identifier 'option' out of scope,
when I checked the object "option" after running the code. It was not a run
time error, I did a quick watch.

I appreciate your patience and help in trying to help me figure this out.

Hi,
so finally it was solved or you r still getting some errors?

Mike Collins said:
I had to change your code where you had the "as TextBox" because it caused an
error to the following:

this.dgDropDownMenus.EditItemIndex = e.Item.ItemIndex;
TextBox option =
(TextBox)dgDropDownMenus.Items[this.dgDropDownMenus.EditItemIndex].FindControl("txtName");

Then I got the following error: error: identifier 'option' out of scope,
when I checked the object "option" after running the code. It was not a run
time error, I did a quick watch.

I appreciate your patience and help in trying to help me figure this out.

Manish Bafna said:
Hi,
Try this one:
this.dgMenus.EditItemIndex = e.Item.ItemIndex;
dgMenus.Items[this.DataGrid1.EditItemIndex].FindControl("txtName") as TextBox

Sorry for the incomplete response. Below is the event that is running, and I
am getting an error on the first line of the method "string option..."

private void dgDropDownMenus_EditCommand(object source,

Hi,
can you please tell at which line you are getting this error?Most probably
you would be using this line of findcontrol in update event of DataGrid.If
you give details as to where r using this code of findcontrol or in which
event u r using then only i would be able to help you out.

Thanks, but I get an error: Object reference not set to an instance of an
object. Any idea on why that is happening?

:

Hi,
It should be:
DataGrid dgDropDownMenus= (DataGrid)sender;
if(e.Item.ItemType.ToString() != "Header" && e.Item.ItemType.ToString() !=
"Footer")
{
string option = ((TextBox )e.Item.FindControl("txtName")).Text;
}

Although i have written this code for Datagrid, you can use same for
gridview with little or no modification.

Hi,
I think the error u r getting in quick watch is the bug in the microsoft
product.See below link:

I think you r now able to get text of textbox in datagrid.
